A clinical RCT of 60 patients with chronic aplastic anemia found astragalus injection added to standard care produced a significantly higher total effective rate (83.3% vs 66.7%, p<0.05) via immune modulation. In myelosuppressed anemic mice, astragalus injection promoted erythroid and megakaryocytic progenitor cell differentiation via antiapoptotic Bcl-XL upregulation.
Clinical studies in China document astragalus reducing the frequency of angina attacks and improving myocardial ischemic injury in patients with coronary heart disease. AS-IV has been shown in a systematic review of 18 preclinical studies to significantly reduce myocardial infarction size and improve ejection fraction. A registered RCT has evaluated astragalus injection in stable coronary heart disease with angina as an outcome measure.
Astragalus constituents, especially formononetin-mediated Nrf2/HO-1 pathway activation and AS-IV, potently reduce reactive oxygen species (ROS) generation across multiple organ systems. Both in vitro and in vivo evidence demonstrates restoration of superoxide dismutase (SOD), glutathione (GSH), and catalase activity. This antioxidant action underlies many of astragalus's downstream organ-protective effects.
AS-IV activates telomerase and preserves endothelial telomere length, directly opposing vascular senescence and atherosclerosis. Animal studies show AS-IV reduces lipid profile markers (TC, TG, LDL-C) and atherosclerotic plaque pathology. Astragalus improves endothelial function partly via nitric oxide–cGMP-mediated vasorelaxation.
Astragalus membranaceus has NF-κB inhibitory activity relevant to asthmatic airway inflammation, as documented in a PMC review of herbal medicines for asthma.
